The error message to include in the generated HTML markup.

Return Value

Type: SystemString

Remarks

Use the CreateErrorDesignTimeHtml method to create HTML markup to display an error message for a control at design time. The value for errorMessage specifies a localized string that is displayed to the user of the control at design time.

The ControlDesigner class implementation of the CreateErrorDesignTimeHtml method returns a table with two rows, as follows:

  • The first row contains the type name and site name for the Component property of the ControlDesigner object.

  • The second row contains the input error message string.

To generate HTML markup for an error message with an associated exception, use the CreateErrorDesignTimeHtml(String, Exception) overload. To generate HTML markup for an exception without specifying a localized error message, use the GetErrorDesignTimeHtml method.

Notes to Inheritors
